Perioperative stroke is a devastating complication after cardiac surgery. In an attempt to minimize this complication, many cardiac surgeons routinely preoperatively order carotid artery duplex scans to assess for significant carotid stenosis. We hypothesize that the routine screening of preoperative cardiac surgery patients with carotid artery duplex scans detects few patients who would benefit from carotid intervention or that a significant carotid stenosis reliably predicts stroke risk after cardiac surgery. ⋯ The majority of postoperative strokes after cardiac surgery are not related to extracranial carotid artery disease and they are not predicted by preoperative carotid artery duplex scan screening. Consequently, universal carotid artery duplex scan screening cannot be recommended and a selective approach should be adopted.

The adjunctive use of a preoperative cerebrospinal fluid (CSF) drain and/or left subclavian artery (LSA) bypass for thoracic endovascular aortic repair (TEVAR) to minimize neurologic complications remains controversial. ⋯ Our use of adjunctive procedures for TEVAR demonstrated better SCI results compared with those of prior reports of selective CSF drainage when SCI arises. Our approach was associated with improved 1-year survival. Preoperative CSF drain placement allows for rapid, intensive therapy for SCI and should be considered when clinically feasible.

We sought to evaluate the incidence, epidemiology, and factors associated with surgical site infections (SSIs) after lower extremity revascularization procedures involving groin incisions and determine outcomes based on SSI status. ⋯ The incidence of postoperative surgical site complications after lower extremity revascularization procedures involving a groin incision was 31% and was significantly associated with blood transfusion, postoperative seroma or hematoma, dyslipidemia, and statin usage. After adjusting for differences in patient and operative variables, postoperative seroma or hematoma was an independent predictor of SSI. Patients with a SSI have a longer duration of hospitalization and higher reoperative rate. Additional prospective cohort studies are warranted to delineate ways to decrease the rate of SSI.

Case Reports
Excision of a permanent inferior vena cava filter with multiple vena caval perforations.
Perforation of an inferior vena cava filter by one the filter device hooks is a recognized possible complication of this device. We describe a case of surgical excision of a permanent inferior vena cava filter associated with multiple perforations of surrounding structures by each of the 6 hooks of the device. Structures affected include the third lumbar vertebral body, transverse mesocolon, the infrarenal aorta, the duodenum, and the psoas muscle. A thorough understanding of the filter design and adequate preoperative imaging were vital in planning the safe surgical excision of this device.

To determine whether the formation of an integrated vascular surgery residency (0 + 5) has negatively impacted the case volume and diversity of the vascular surgery fellows (5 + 2) and chief general surgeons at the same institution. ⋯ At our institution, the introduction of a 0 + 5 vascular residency has correlated with a modest drop (15%) in overall case volume for the 5 + 2 fellows, but the number of primary cases have actually increased slightly and they continue to meet or exceed Accreditation Council for Graduate Medical Education requirements and national 50th percentile rates. General surgery residents' vascular volumes, by contrast, have remained stable, and interest in vascular surgery by residents has increased. Our integrated vascular residents are projected to exceed the fellows' 50th percentile case volume and diversity targets during their residency experience.
